Vibration modeling of the CMP process, May-Jul, 2010
Guides: Prof. Satish T Bukkapatnam & Prof. Ranga Komanduri
Dept. of Mechanical and Aerospace Engg., Oklahoma State University (OSU), Stillwater, OK, USA
- Worked on the development of a deterministic physical model of the Chemical Mechanical Planarization (CMP) process which attempted to explain the sources of the bursts and other non-linear behaviour that are typically observed.
- Developed the simulation in Simulink and conducted experiments on a Buehler grinder polisher to develop and verify the model.

Efficiency improvement in steam and compressed air circuits, May-Jul, 2011
Company: ITC Ltd., Location: Guntur, Andhra Pradesh, India
- Worked in a tobacco Green Leaf Threshing (GLT) factory.
- Applied a systems approach of study to analyze the steam and compressed air usage patterns in the plant and suggested improvements based on the best practices in industry. Also, redesigned the entire compressed air distribution layout to meet the future increase in demand.
- The improvements account for an annual saving of ₹ 0.8 million.
- Offered a job with the company upon graduation.
Virtual collaboration between design and manufacturing
Event: Young Engineers Visitation Program (YEVP), Jun 2011
Organizer: Lockheed Martin Corp and Indo-US Science & Technology Forum (IUSSTF)
Venue: Lockheed Martin Center for Innovation, Suffolk, VA, USA
I was nominated for the program due to our team’s performance in the DRDO Student Robot Competition 2010. Our team along with the other top five performers participated in this program.
The theme of our part of the program was to address the 3 major challenges faced in manufacturing:
- collaboration between design and manufacturing,
- optimization of design of factory and processes, and
- communication of manufacturing status to design and product management teams.
We Presented a solution for the above problem, developed in the Second-Life environment to an audience including several scientists from Lockheed Martin.
As the team leader, my role was to:
- Bring the team members together, establish a structure for teamwork.
- Act as a facilitator for communication between the problem statement organizers (“customers”) and the team. Ensure that we have a shared understanding of the same thing.
- Work with the team to understand the customer needs and layout a problem definition.
- Distribute work evenly among the team members to achieve the goals.
- Directly contribute in the Second Life object creation and scripting for the factory simulation.
- Mastered Second Life object creation and scripting
- Created a visual representation of a factory floor to increase engineering-manufacturing collaboration
- Created a simulation that can optimize the factory design for any number of outputs
Our team was awarded the prize for “Virtual Collaboration Conceptualization”.
